In 1984, two sisters, Inês and Marta, fall into the strong currents of a river while fighting each other over a doll. Their father manages to save Inês, the oldest of two, but Marta is nowhere to be found and is presumed dead. Their mother, pregnant of a boy, witnesses everything, and grieves the death of her husband (who died rescuing his daughters), and supposedly, of his youngest daughter.
